The second generation A8 expanded on the offering of the previous generation in every way. The wheel base increased, the available engine choices grew larger with the introduction of the 6.0L W12 and the wheels and brakes grew to keep up with the additional power and weight. An airbag suspension was introduced as well to offer a dynamically changing ride height, the control module for this system can be modified for those looking to lower their car. In 2006 the A8 was facelifted to the new "shield" style grill among some other changes.
